there is a perfect balance with these cars as to what's too thin, and what becomes too think for the Vanos.
If only a 15W50 existed up north of the border... *sigh* Apparently they don't think people choose their oil based on temperature. Mobil1 has 5W50 instead of 15W50. Castrol has a 10W40 and that's about the max.
Amusingly, Castrol and Mobil1's oil selector says 0W40 for this car on their Canadian Web site. I'd never put a zero-weight in here, but 5W and 10W is pretty unavoidable sadly.

We get (complete line from each)
Mobil 1 0W-40
Mobil 1 5W-20
Mobil 1 5W-30
Mobil 1 5W-50
Mobil 1 10W-30
Castrol Synthetic 10W30
Castrol Synthetic 5W50
Castrol Synthetic 5W40
Castrol Synthetic 5W20
Castrol Synthetic 0W30
Castrol Synthetic 5W30
AND only a fraction of those are actually B3/A3 approved or whatever the API spec is.

And for the record, it's August 2nd today, and it's 38C which is just over 100F.

I am running M1 Ow40. Seems like the car sounds normal. I don't worry about the low number too much. At any rate, our MDX is running 5w20 and it can tow 3500 pounds.

All oil manufacturers are different but in my experience, 5wXX oil has been too thin, I run 15w50 now.

What aspects of engine protection makes the low number too thin, assuming you are talking about synthetic?

FYI: Mobil1 5w30 is really more of a 5w20. The 0w40 is a very good oil, so long as you can get over the psychological barrier.

salty.. do you run authentic oil, or the counterfeit stuff sold by the hell's angels?

and 3500 lbs... dude.. thats embarassing? i bet the M3 could tow that..... any idea what a REAL payload is>?

and besides.. who cares what oil you run in a totally different vehicle. My 85 '250 can tow around 10k lbs.. i run 20w50 spiked with straight 30... what the hell does that have to do with anything?

E46 towing capacity in Europe is up to 1900kg. (Depending on engine.) I'd expect that the E36es were rated fairly similarly, given what I saw them pulling last time I was in England.

I will have to disagree with your irrational fear of 0w40, though.

Badgtho: so would it be safe to say this self-proclaimed oil expert below running 0w20 in his Ferrari is insane? He has the full backing of Ferrari North America in his oil testing over on the Ferrari Chat forums

is an E36 a ferrari? dang.. if so.. i was seriously Mislead.

the is nothing wrong with 0w oil in many cars. in a 10 yr old M3.. there is. i think there needs to be a lesson in reading for comprehension here.


so far.. we have Salty's arguement resting on his Honda SUV.. and you, comparing a 10 yr old BMW to a ferrari.

nice debate. ... anyone else? my old lawnmower took non-detergent sae30 oil.. who runs that in their M3... Toro says its OK.. so i think it must be fine in my M3.

0w and 5w are NOT "thin". Those are just cold pumpability ratings -- and actually you want them to be as low as reasonably possible so that the oil flows well at low temps and gets everywhere it needs to go in the engine as quickly as possible on a cold start.

The only possible problem would be a wide spread in the numbers; for example, with a 40-weight or a 50-weight, 0w or 5w would not be a good choice because achieving such a combination of ratings requires heavy use of viscosity index improvers that at best would compromise performance and at worst may shear and alter the viscosity of the oil, possibly leaving deposits in the process. But since my car sees only street duty, and since this oil is a top-shelf synthetic, 30-weight is fine (this particular one is close to a 40-weight anyway), and therefore 5w is fine.

That was a dino oil from the mid-90s. Modern top-shelf synthetics are a very different story.
